broad answer. There's tons of suppliers. Go to "Circuit Assembly" magazine web site and look-up flux suppliers in the "Buyers Guide." Broad line suppliers are Kester, Alpha ... They will make you answer: I'm joining bla, bla, bla metals, using b

Is it possible to have zero flux or paste spattering for all smt reflow pcbs. We are seeing around 0.4% of flux spattering and looking forward to zero defect.

We see spattered(spitting of flux or solder to nearby area) solder/flux on gold fingers.We view the gold fingers area under 30x before reflow and it is cleaned but after reflow we see flux droplets or solder on gold fingers. We tried to changed a new

I don't believe you'll get an exact zero flux with no-clean pastes. Water soluable yes, but I don't see it happening with no-clean; at least not this year. As for spatter, you should be able to control this. Can you define what you call "spatter"?

Search the fine SMTnet Archives for background on solder on gold fingers. As we recall: * Paste selection * Proper reflow recipe tuning ... are important.
